Hey I just updated from Precise Maneuver 2.4.1 to 2.4.2 (finger fumble the version number I was talking about when I first wrote this today) (I really do me 2.4.1 and 2.4.2) , now I get issues where I can not create Maneuver nodes after a playing for a while. Restart of KSP seems to fix the issue. Any one else see something like this. Happens again I'm going to roll back to 2.4.1 to see if the issues goes away. Love the MOD!
